RAILWAY CAR Filed June 13, 1950 Patented Jan. 12, 1932 PATENT OFFICE WILLIAM E. WINE, OF TOLEDO, OHIO RAILWAY CAR Application filed June 13, 1930. Serial No. 480,879.

My invention relates to railway cars and more particularly to the lading discharge doors of cars of the hopper type.

Heretofore it has been customary to provide a hopper door with inwardly pro ect ng marginal flanges adapted to cooperate with the portions of the hopper bounding its lad ing discharge opening to prevent the escape of fine lading from the car when the door is supported in closed position. In doors of this type considerable difliculty has been experienced in causing them to assume a fully closed position due to fine particles of coal becoming lodged and pocketed in the angle formed by the main body ortion of the door and the lower marginal ange. Due to the presence of moisture in the lading this pockcted coal becomes caked and hardened thereby making it practically impossible for the door to assume such a position that the escape of. fine lading will be prevented. Furthermore, complete closure of the door is often rendered difiicult by comparatively large pieces of lading such as coal, rock ballast and the like becoming lodged'between the lower marginal flange and the main body portion of the door.

The principal object of the invention is, therefore, to provide the lower portion of the door with means whereby the pocketing of lading to such an extent as to interfere with complete closure of thedoor is prevented.

A primary feature of the invention consists in forming the lower portion of the door with two inwardly extending reinforcing portions arranged in spaced relation affording a recess to receive the adjacent portion of the hopper when the door is in closed position.

Another and more specific feature of the invention is to provide the lower portion of the door with an inwardly extending margin al flange adapted to overlap the outer face of the adjacent portion of the hopper and to further provide it with an inwardly extending corrugation adapted to overlap the inner face of the said portion of the hopper.

Other features of the invention residing in advantageous forms, combinations and relations of parts will hereinafter appear and be pointed outin the claims.

In the drawings illustrating a preferred embodiment of the invention:

Figure 1 is a plan view of the hopper door.

Figure 2 is a sectional view taken on :hne 22, Figure 1.

Figure 3 is a longitudinal vertical sectional view of a portion of the hopper showing the relation of the door thereto.

Figure 4.- is an enlarged view of the lower portion of the construction illustrated in Figure 3. I

For the purpose of illustrating the invention the door 1 has been shown as applied to a cast metal door frame 2 of the type disclosed in my Patent No. 1,705,147, dated March 12, 1929. The door frame is rigidly secured to adjacent portions of the hopper 3 and it is preferably formed with a plurality of outwardly projecting flanges 4 bounding the lading discharge opening 5.

Although the door may be made of cast metal it is preferred to form it from a single sheet of metal having a main body portion 6 and aplurality of inwardly extending marginal flanges 7. The'door may be mounted upon the car in any suitable manner and for this purpose it may conveniently be provided with two hinge straps 8 secured to the outer face of the door by rivets 9. Each of the hinge straps is formed to receive a pin 10 removably mounted in lugs 11 which may advantageously be integrally formed with the upper portion of the door frame 2.

The marginal flanges 7 of the door are respectively adapted to overlap the outer faces of the adjacent flanges 4: of the door frame when the door is in closed position. As may be seen in Figure 3 the door is disposed in a plane forming an oblique angle with the vertical when in closed position and any suitable mechanism (not shown) may be employed for maintaining it in this position.

Formed in the lower portion of the door is an inwardly extending reinforcing member 12, preferably in the form of a corrugation, which extends longitudinally of the hinge axis of the door in spaced relation to the lower marginal flange of the latter. The corrugation overlaps the inner face of the adjacent portion of the hopper when the door is in closed position and afi'ords with the lower marginal flange a recess 13 into which the said portion of the hopper extends. Thus it will be seen that when the door is in closed position only a very small quantity of lading may sift between the corrugation and the adjacent portion of the hopper and since this portion of the lading is not directly subjected to the vertical load of the remainder of the lading within the car it will not become caked or packed in the recess formed by the corrugation and lower marginal flange of the door. In other words the corrugation forms,

in effect, a seal with the adjacent portion of the hopper or door frame preventing any substantial quantity of lading from moving into the recess 13. The corrugation preferably projects a sufficient distance from the plane of the door so that when the door is in open position permitting lading to discharge from the car it is impossible for large pieces of lading to rest or lodge upon the lower marginal flange which would thereafter prevent the door from assuming fully closed position. Moreover, to prevent particles of lading from being retained by the corrugation itself the upper portion thereof inclines downwardly at an obliqe angle to the plane of the door.

The portion of the corrugation immediately adjacent the door frame is rounded or beveled as at 14 so as to engage the hopper to wedge or force the door upwardly in the event it has sagged upon its hinges. Furthermore, when the door is in closed position the corrugation acts'as a stop limiting downward movement of the door in the event of sagging.

From the foregoing it will be perceived that the door in addition to being adequately reinforced is so formed as to prevent the lading from interfering with closing'move- 3 ment thereof.

I claim: i

1. In a railway car having a hopper provided with a lading discharge opening, a door for closing saidopening, said door being disposed in a plane forming an oblique angle with the vertical when in closed position, the

.lower portion of the door being provided with an inwardly extendingmarginal flange and an inwardly extending corrugation arranged in spaced relation to the latter to afford a recess into which the adjacent portion of the hopper is adapted to extend when the door is in closed position. i

2. In a railway car having a hopper provided with a lagling discharge opening, a door for closing said opening said door beingdisposed in a plane forming; an oblique angle with the vertical when in closed position, the lower portion of the door being provided with an inwardly extendingmarginal flange adapted to overlap the outer face of the adjagation adapted to overlap the inner face of the'said portion of the hopper.

3. In a railway car having a hopper provided with a lading discharge opening, a hinged door for closing said opening, said door being disposed in a plane forming an oblique angle with the vertical when in closed position, the lower portion of the door being provided with inwardly extending reinforcing members arranged in spaced relation affording a recess to receive an adjacent portion, of the hop er when the door is in closed position, one 0 said members constituting a marginal flan e adapted to overlap the outer face of the said adjacent portion of the hopper and the other of said members overlapping the inner face of the said adjacent portion of the hopper and having a downwardly inclined portion extending at an oblique angle to the plane of the door.

ii:- In a railway car having a hopper provided with a lading discharge opening, a hinged door for closing said opening, said door being disposed in a plane forming an,

oblique angle with the vertical when in closed position, the lower portion of the door being provided with an inwardly extending marginal flange and an inwardly extendlng corrugation arranged in spaced relation to the latter to afford a recess into which the adja-.

cent portion of the hopper is adapted to extend when the door'is in closed position, said corrugation being provided with a beveled portion adapted to cooperate with the said adjacent portion of the hopper to wedge the door upwardly in the event of sagging of the door on its hinge pintles.

In testimony whereof I afiix my signature.
